Abstract
An oscillating wiper for a tufting machine has a bristle brush for sweeping loops shed by the looper away from the needle path and prevents the loops from springing back into the needle path thereby preventing sew-thru and tagging. The wiper is operatively carried by the knife shaft and oscillates therewith in timed relationship with the formation, seizing and shedding of the loops by the looper. The tufting machine disclosed is a level cut/loop machine in which the looper has a selectively pivotable gate member which opens to allow loops thereon to be cut by the knife and is selectively closed to shed loops to form uncut pile. The bristles of the wiper act on the uncut loops.
